TECHNICAL FIELD

This invention relates to the field of character library technology, and particularly, to a method and apparatus of building an intermediate character library.

DESCRIPTION OF THE RELATED ART

When the font creation person is creating a font, modifying a font, and performing an operation on contour points, it is often required to add, delete or drag single-contour(s) of a character and contour points on the single-contour one by one, which may cause the operation to be more trouble, especially when multiple single-contours need to be processed at the same time (for example, it is required to drag the position of one radical, or even to replace the radical). Because many radicals are each comprised of multiple single-contours, in order to keep relative positions of the contours of one radical unchanged during moving or replacing the radical, usually it is difficult to achieve the expected effect by moving or replacing the respective single-contours one by one, and such operations are very troublesome.

Currently, the common solution is that, multiple single-contours are simultaneously selected by clicking and picking the multiple single-contours one by one with a software (usually, the font creation tool), and then the selected multiple single-contours are processed as a whole. With such solution, it will take much time and work to click and pick the multiple single-contours one by one in the case of a large number of the single-contours, and thus, its efficiency is very low and it is easy to make mistakes.

The original character library creation unit may be configured for creating the original character library.

Embodiment 2

As shown in FIG. 1, this embodiment provides a method of building an intermediate character library, comprising the following steps:

Step S1: creating an original character library.

In the present embodiment, the original character library is created by a font creation tool. Specifically, the created original character library is a Chinese character library. That is, the characters in the original character library are Chinese characters.

The original character library stores basic information of this character library and contour information of Chinese characters therein.

Further, the basic information of the character library comprises the number, character codes, lengths and widths of the Chinese characters in this character library, and the contour information of the Chinese characters mainly refers to contour data of the Chinese characters.

In the original character library, each Chinese character comprises one or more single-contours (usually the single-contour is a stroke of the character), and each single-contour may comprise multiple contour points.

Step S2: acquiring the original character library.

In the present embodiment, the original character library created in the step S1 is opened by the font creation tool, so that the original character library is acquired.

The font creation tool is required to have the ability to open the original character library, and to read, display, process and store the original character library.

Specifically, the font creation tool can read Chinese characters in the original character library, can identify contour data of the Chinese characters in the original character library, and can display one or more single-contours in each of the Chinese characters and contour points on each single-contour. Furthermore, the font creation tool can perform some basic operations on the single-contour and the contour points, such as, selecting and dragging the single-contour or contour points, and the like. Upon opening the original character library, the font data (i.e., contour data) of the character in the original character library is displayed in a display interface, for use in subsequent operations performed by the operator. The font creation tool further can save the modified font data of the character, and can store the added contour information and structure information of the character components into the original character library.

In the present embodiment, the font creation tool is also required to have the ability to identify contour information and structure information of respective character components obtained by dividing the Chinese character and to store the contour information and structure information of the character components into its memory. Further, the structure information mainly comprises mapping relation between the character components and the character corresponding to the character components, and information regarding positions of the character components in the corresponding character. Thus, with the built intermediate character library, as there is contour information of the respective character components stored in the intermediate character library, the font creation tool can select the contour data of one character component during the displaying, i.e., can perform operation on one character component as a whole. For example, the entire character component can be moved, copied, replaced, modified or the like as a whole. When the character component is selected, it can be seen which contours are contained in this character component. Further, because the structure information of the character component can also be stored in the intermediate character library, when necessary, the character component can be searched for or replaced, so as to find the same component at the same position.

Step S3: reading one arbitrary character in the original character library, and determining whether this character can be divided into two or more character components or not; if so, proceeding to step S4; otherwise, proceeding to step S6, which determines whether there is any undivided character in the original character library and, if so, returns to the step S3 to read a next character in the original character library.

Herein, the term “character component” means a relatively independent structure unit in a Chinese character, which can be obtained by various dividing methods. For example, the character component may be an individual character, such as the character components, i.e., the character “

” and the character “

”, obtained by dividing the character “

” into “

” and “

”. The character component may also be a stroke, such as horizontal stroke, dot stroke and the like. The character component may also be a “radical”, such as the radicals “

”, “

”, “

” and the like. The character component may also be a constituent part of the Chinese character, such as the lower part “

” of the Chinese character “

” as one character component, and the remaining part “

” as another character component, which is obtained by removing the part “

” from the Chinese character “

”.

Specifically, the standard for determining whether the Chinese character can be divided is that: whether the Chinese character can be divided into two or more components. If so, it indicates that this character can be divided; otherwise, this Chinese character cannot be divided.

Whether the Chinese character in the original character library can be divided is determined mainly based on the structure of this Chinese character itself. If the current Chinese character can be divided into two or more character components, it indicates that this Chinese character can be divided, and then proceeds to step S4. If the current Chinese character cannot be divided, such as the Chinese character “

”, “

” or the like, the font creation tool proceeds to read a next Chinese character.

Step S4: after determining the character can be divided in step S3, dividing the character into two or more character components to acquire contour information of the respective character components after the dividing.

Specifically, in the present embodiment, the Chinese character is divided by the font creation tool.

Further, dividing the Chinese character can be done according to the structure of the Chinese character itself. Specifically, by reference to structure code of IDS attribute in Standard ISO 10646, a Chinese character can be divided according to the IDS attribute. The IDS attribute is an attribute that classifies structures of the Chinese characters, and with it, the Chinese characters can be classified into different structure styles, such as, left-right, top-down, left-middle-right, fully surrounded, not fully surrounded structures and the like. For example, if the structure of the Chinese character is the top-down structure, then this character can be divided into two character components, i.e., a top component and a down component. For example, the Chinese character “

” is divided into two character components “

” and “

” which also belong to the Chinese characters. If the structure of the Chinese character is the left-right structure, then it is divided into two character components, i.e., a left component and a right component. For example, the Chinese character “

” is divided into two character components “

” and “

” which also belong to the Chinese characters, and the Chinese character “

” is divided into two character components “

” and “

”. If the structure of the Chinese character is the surrounded structure, it is divided into two character components, i.e., the surrounding part and the surrounded part. For example, the Chinese character “

” is divided into two character components “

” and “

”. If the structure of the Chinese character is the top-middle-down or left-middle-right structure, it can accordingly be divided into three character components. For example, the Chinese character “

” can be divided into three character components, i.e., “

”, “

” and “

”, the Chinese character “

” can be divided into three character components, i.e., “

”, “

” and “

”, and the like.

The process of dividing the Chinese character actually is for selecting one or more single-contours contained in each of the character components in this Chinese character. That is to say, one or more single-contours contained in each of the character components obtained by the dividing can be selected all together as a group.

Step S5: establishing and acquiring structure information of respective character components in the character which has been divided in the step S4.

In the present embodiment, establishing the structure information of the character component specifically comprises, establishing a structure code of the character component. Specifically, the structure code of the character component comprises: the character code of the character corresponding to this character component, component code of this character component itself, and position code of this character component in its corresponding character.

In the present embodiment, the character code employs the Unicode code. Of course, the character code may also employ other common Chinese character codes.

Because the character component obtained by dividing the character may be another character, a radical or a stroke, the component code of this character component itself may be set according to different type of the character component. Further, the character component usually comprises multiple single-contours each of which in turn comprises multiple contour points.

When the character component obtained by the dividing is another character, the component code of this character component itself may be set to the character code of said another character.

When the character component is a radical or a stroke, that is, when the character component obtained by the dividing is not a Chinese character, the component code of this character component itself may be set to a freely-defined code, which is not identical to the existing character codes of the Chinese characters, and need to be set within a range beyond the range of normal character codes of the Chinese characters. However, the freely-defined code may have a certain meaning, e.g., the component code may indicate the position of this character component in its corresponding character and the glyph of the character component. Specifically, each of single-contours in this character component may be marked by adding an index to it. As each of single-contours in a single Chinese character has its index value, each of the character components may be consisted of contours represented by some index values, and the component code of this character component itself may be set to be comprised of the index values added to respective single-contours.

In this way, it can be clearly known that the Chinese character subject to the dividing process is comprised of how many character components, and each of the character components is comprised of which single-contours.

As to the position code, it is defined mainly based on the position of the character component in the corresponding character.

For example, for the Chinese character “

” in the original character library, after the dividing process, the obtained character components are “

” and “

”, and accordingly the structure code of the character component “

” may be set to be “7C7B7C7301”, and the structure code of the character component “

” may be set to be “7C7B592702”. Specifically, the higher four bits (i.e., “7C7B”) of the structure codes of the two character components represent the Unicode code of the Chinese character “

”, the middle four bits (i.e., “7C73” and “5927”) represent the respective Unicode codes of the Chinese characters identical to the two character components, and the lower two bits (i.e., “01” and “02”) represent the respective position information (i.e., the position codes) of the two character components in the corresponding Chinese character “

”, where “01” indicates the top component in the top-down structure, and “02” indicates the down component in the top-down structure.

After dividing a Chinese character and setting its corresponding structure information, the contour information and structure information of the character components obtained by the dividing process can be temporarily stored into the memory of the font creation tool.

Step S6: determining whether there is any character which has not been divided yet in the original character library. If so, return to the step S3, so as to repeat the steps S3-S5, thereby acquiring contour information and structure information of a next character in the original character library.

After dividing a Chinese character and setting its corresponding structure information, its contour information and structure information can be temporarily stored into the memory of the font creation tool. Then, proceed to dividing a next character.

Step S7: storing the contour information and the structure information of the character components into the original character library so as to build an intermediate character library on the original character library. After storing the contour information and structure information of the character components of all the characters which can be divided in the original character library into the original character library, the original character library forms the intermediate character library.

If there is no Chinese character in the original character library, which needs to be divided, the contour data and structure codes of the characters stored in the memory of the font creation tool need to be stored into the original character library. This requires the font creation tool itself having such ability of storing the contour data and structure codes of the characters completely into the original character library, so that the original character library forms the intermediate character library.

When all the Chinese characters have been divided into the character components, those above-described information (including the contour information and structure information of the character components) may be stored into a new file. When writing those above-described information into the new file, it is better to also write the hierarchical relationship of “Character→Component→Contour→Point” into this file, for facilitating subsequent reading. Therefore, when creating a font by using the font creation tool, by reading this file so as to read this hierarchical relationship, it will be better understood which specific contours constitute the character component. Thereby, the information and data related to the character component can be directly read out from this file during subsequent utilization.
